data comes in on com1 from a puck-GPS, Garmin
AIS data comes in from a Raymarine
AIS 500 on com6 via an NMEA
block at 3800 baud.
I un-installed OpenCPN 3.0 and reinstalled 2.5 to check if my boat was showing in the AIS Target List. As I mentioned earlier, it does. I have reinstalled OpenCPN 3.0 and my boat still shows in the AIS Target List, but the AIS icon no longer flashes a warning.
When I turn the AIS on, about a minute later, a green dot appears in the bottom right of the AIS button. The triangular boats were turning red yesterday.
I am fortunate enough to be in a nice quiet anchorage so the only AIS clutter is myself and one other boat, which is outside my 2NM CPA alarm
Thank you for your help, I really appreciate it.
